Unless I read wrong. You stated that KHP uses the MAC ID of the ethernet adapter, not Microstudio. I encountered the same problem. I don't have khp. I only have Microstudio 2.506. it gave me the same message when I tried to re-install Microstudio onto my new computer. also I haven't received any new emails with the download link for 2.517 or better?
